Studies have not adequately addressed the influence of fatigue, which is considered a major risk factor for hamstring injuries. Therefore, this study aimed to clarify how a muscle fatigue condition affects the success of hamstring injury prevention programs in sprinters. The study subjects were 613 collegiate male sprinters. They employed submaximal/maximal running for a large number of runs and supramaximal running for a small number of runs in daily training. The hamstring injury prevention program had become the most effective strategy in the past 24 seasons of track and field for preventing hamstring injuries. The number of sprinters who experienced hamstring injuries in three periods over the 24 seasons was recorded. The incidents of hamstring injuries during supramaximal running per athlete-seasons were 137.9, 60.6, and 6.7 for Periods I, II, and III, respectively, showing a significant decline (p < 0.01). Furthermore, the incidents of hamstring injuries during submaximal and maximal running per season showed no significant change. The results of this study indicate that by inducing muscle fatigue, a small number of runs makes hamstring injury prevention programs effective.
研究尚未充分探讨疲劳的影响，疲劳被认为是腘绳肌损伤的一个主要危险因素。因此，本研究旨在阐明肌肉疲劳状态如何影响短跑运动员中腘绳肌损伤预防计划的成功率。研究对象为 613 名男性大学生短跑运动员。他们在日常训练中采用次最大/最大跑和超最大跑进行大量跑和少量跑。腘绳肌损伤预防计划在过去 24 个田径赛季中已成为预防腘绳肌损伤最有效的策略。记录了 24 个赛季中三个时期发生的腘绳肌损伤的短跑运动员人数。运动员-赛季期间超最大跑中腘绳肌损伤的发生率分别为第 I 期、第 II 期和第 III 期的 137.9、60.6 和 6.7，呈显著下降（p<0.01）。此外，每个赛季的次最大和最大跑中的腘绳肌损伤发生率没有显著变化。本研究结果表明，通过诱导肌肉疲劳，少量跑可以使腘绳肌损伤预防计划有效。
